ft2/day
1 cm2/s = 93.000186 ft2/day
Conversion Basis
The coefficient of consolidation has dimensions of length squared per time and controls the time rate of one-dimensional primary consolidation. Laboratory results may be reported in cm2/s, m2/year, or ft2/day.
target cv = source cv x source-to-square-meter-per-second factor / target factor
Common Examples
- 1 cm2/s = 93.0002 ft2/day
- 1 m2/year = 0.0294703 ft2/day
- 1 mm2/s = 0.0864 m2/day
Engineering Use and Limitations
- cv may vary with stress level and the interpretation method used on an oedometer increment.
- Drainage path length is squared in consolidation time calculations, so geometry errors can dominate the result.
- This conversion does not change the logarithm-of-time or square-root-of-time interpretation basis.
